The Let L-610 is a prototype aircraft for the Czech civil aircraft manufacturer Let Kunovice made in 1988–1997.
Design and development
In the late 1970s, after the success of the LET
LET's L-610 was designed as a twin engined turboprop aircraft powered by the new Czech engine, Walter M602, with a seating capacity of 40. Flight testing was delayed by engine development taking longer than airframe development. Eventually the 1,358 kW (1,822 shp) turboprop engines were finished and the aircraft first flew on 28 December 1988. No aircraft was ever delivered to any commercial customer, although one aircraft was shown in Aeroflot markings during the Paris Air Show in the 1990s. One Let 610 M was delivered to the Czech Air Force,[1] to support manufacturer's certification and test flights process.
